Beit known that I, CHARLES E Dnvisf, a

citizen of theA United States, residing at Chicago, in the 'county ofCook and State of 1llinois,`hav'e invented a certain new and usefulImprovement in Trucks, of which the following is a specification.

My invention relates to trucks', and the par# ticular form in which Ihave illustrated the same is a form peculiarly adapted for the purposeof handling mining-machines. In Such Acases the mining-machine,whichlias considerable weight, is lying upon the ground on or near thetrack upon which the truck runs. The truck to travel properly shouid insuch cases have four wheels.,` It is commonly equipped with -a devicefor drawing the mining-machine along the body oi' the truck until commonpractice0 to push the vtruck 'forward until its projecting forward endis near the mining-machine. 'Thetruck is then lifted at the rear end,swingingon its forward axle until lthe forward end of the truck hasreached the ground in close proximity to the miningmaehine. By nowoperating the windlass on the rear end ofthe truck the chain, which hasbeen 'previously4 hooked into the mining-machine,is wound ontheWindlass, the mining-ma chineis drawn up on the truck, and when it hasreached the proper position, so thatthe center of gravity is. slightlyrearward of the forward truck, the rear wheels oi' the truck'fall downinto their normal position. If the device isskilfully operated, thesewheels will fall upon the track; if not, there will be some diiiicultyinv swinging and lifting the truck until its four 'Wheels are properlyon the track. M oreo'yer, it requires great eort sometimes to raise therear endof the truckand bring it in sucli proper position. If the roofofthe mineis low` the rear end of the truck is likely to come up nearthe roof, thus interfering with thc operation of the windlassandfotherwise hindering and making dicult the task of handling thetruck. -Moreover,' if the roof is low, the.

effort imposed on the miners ,to lift the rear end of the truck isgreater than under other To y portieri of the 'frame conditions.Becauseof these other diboultiesl have been ledv to make the inventionFigure' l is a side view of the truck witho parts shown in a secondposition by dotted lines. Fig. 2 is a plan view,` and Fig. 3 is asection on the line 3 3 of Fig. 2. i l f Like parts are indicated bythesame' letters in all the figures.

A Aare the aXles,B E the Wheels, and C C the rails on whichV the wheelsrun. axles are joined together by a framework. consisting of the bars DD., and the rear stationary portion of the' truck is composed of thewide side bars E E and'cross-pieees F F. Reawardly projecting from thisstationary part are the arms (i G, in whichris journaled the windlass H,having on'rone end the ratchetdvheel'd, associated with the Weighted'dog K, which keeps the Windflass fromreverse rotation.v Loosely.journaled on one' end'of the windless is the arm L, whichl carries thedog K. JVhen the arm is operated, the dog K is moved so as to engagetheratchet-wheel and rotate the windlass. "When` the motion of the arm-isreversed, the d'g K slides over the teeth of the ratchet-wheel.

Mis a cable secured to and adapted to le' Wound on the windlass andprovded'with a' mining-machine or other object-to be loaded.

The two` while the inner portions N2 N2 proceed in a right line.

O 0 arel cross bars or pieces whereby the forward portion of thetruck-body is'made intoa complete structure. This forvi'ard por-l tionis pivoted on the axle at P P.

R is a sliding collar on 'the rear axle, pro-` vided with thetingerS,.ivhich is adapted to overlie the and of the side bar N, and thus lockit ina fixer relation to the frame and forward portion of thetruck-bixlywhen .that is, necessary. T his would benecessary when the itruck is to be movedon the track without 8c' hook M', by which it can bemade fast'to the Y loci; is needed, for the load bridges` the break ibetween the two parte of' the triiclr-body and i body con holds theseparts in position.

lit will be understood that have shown and described simply one form ofmy invention and in doingso have Set out certain parte and relationsthereof; .but i `Wish it to he understood that l doy not thereby desireto limit myself to these particular forms or to thispartcular-emhodiment ot my invention.' 1t must be obvious that the samecan be reaiized in a variety of Structures and that these Structuresmust greatly differ in view of the-particular to which the invention i'sto be applied. The form which I have shown I consider highlysatisfactory for use where the truck is intended to run on ls and Wherethe work to be done is the loading of heavy machinery, such asmining-machines, where they lie low down or upon the ground.

'The use and operation of my invention are perhaps snfhciently indicatedalready. I will add, however, that the truck when the forward portion islocked in position can bc yfreely moved out and inward on the track.

Vvrhen the machine is to be loaded, the truck is moved forward close tothe machine, the lock is released, the forward end drops down and ispushed under the end of'v the miningmechine, the hook is made tast tothe miningmachine, and the windlass is operated. The result, of course,is that-the mining-machine is drawn up the inclined plane formed by theforward part of the truck-body when in this position, and this actioncontinues until the center of ,gravity is a littleto the rear of theforward axle, whereupon the forward part of' tle truck-frame gentlyswings into a horizontal position and tliecontinued action of thewindlase draws the machine along upon and above the rear part of thetruck-body until the machine properly loaded on the truck.

(if course the forward portion of' the truck Lt. In a truck thecombination of a Supporting part with a normally fixed portion of thetruck-body, and a tilting portion of the truckbody, both mounted on auchsupport, and a device on the fixed portion of' the truck-frame adaptedto draw the load over the movable i portion.

could be formed so as to be nicely balanced .on the axle or even so thatits center ot' gravity would'be in the rear of the forward axle;

but i think what l have here shown is the pre-I ferred form.
